Any chance to change power steering feel?

So I am not positive what is involved in "setting" the power steering to the level of "weight" it takes to turn the wheel. Basically having less assist and a more heavy feel. Given the m3 can change to different heaviness of steering, why is it not possible for a tuner to further manipulate this and create heavier steering that so many of us always dream about?

Could be another option in a tune with ability to choose it or stick with the 2 regular choices. Given bmw allows you to toggle between two different ones, I am guessing it is ultimately computer driven as far as how much the pump is working.

Seems like a tuner could do this and really make a profit

The first part is probably true, the second is questionable.

It might take considerable time and effort to reverse engineer this part of the system. How many people do you think would want to take advantage of this? And at what cost?

Doesn't seem like there have been a lot of people asking for this.

However it is one great way to differentiate their tune from others given most of them produce the same gains in hp/torque etc. Choosing a tune is based on preference and there is no better tune necessarily but if one tuner also offered ability to tune power steering feel, I bet that would sway a lot of buyers to go with that one even if it had not previously crossed their mind.

Not possible. I have a 2009 E90, and have posted here many times about the overboosted steering. However, it is more than an overboost problem. The steering rack is also designed in such a way as to decrease feedback and feel.

As I came from a modded EVO MR, I was used to laser-like steering, which the M3 does not have. I have contacted Dinan, Turner, and a number of other professional and local tuners. There is no way to get into the code that controls steering boost. There is no way to design and build a new rack. There is no demand for this, and the tuners have no interest in this mod, or the liability issues.

In light of this, I did some mods to try and help a bit. I have a Dinan Stage 3 suspension, and the camber plates help with turn-in. I'm running Yoka Advan AD-08s, which are a bit stickier than the stock PS2s. However, the overboosted steering with lack of feel is still there, and I'm not happy.

Frankly, the only solution is to buy and EVO, STi, Porsche, or Lotus.

Nope. If you read most major motoring magazines--R&T, C&D, among others, they have all made complaints about the M3 steering feel. Sure it weights up with speed, but the feedback is not great. Do not confuse steering effort with feedback and feel.

Gotta say I wouldn't quote magazines when it comes to describing our cars. In this case, however, I agree with the over-boosted numbness. I have the heavier setting programmed into my M setting and use it often.

I've noticed on my car with increased negative camber I got better steering feel and it also feels less boosted. I'm running close to 3 deg of neg camber - not ideal for tire longevity on the street.

Guess what?--The new R&T that came today has a large feature article on the new twin turbo M5. A major flaw as per the magazine--poor steering.

Light steering feel

I actually noticed the lightness in the steering immediately as I was coming from an E46 M3, which has a much more solid feeling at the steering wheel.

The one nagging side effect to this lighter steering is that I find myself needing to pay closer attention to holding the car in a straight line when I'm just cruising along the highway. Any slight input into the wheel results in the car moving. If I could stiffen it up a bit I would certainly do it. Otherwise, I suppose its just one more thing I'll need to get used to.

That's because it has ELECTRIC POWER STEERING .

I'm very happy with the steering on my M3. Porsche and Ferrari are better, but that's about it in my experience. And it's not far behind those. The important factor is feel and feedback at speed, not in a parking lot. I actually leave mine on the normal setting. Oh, and at least Porsche moved to electric power steering on the 991 and all future models . But just as direct injection, that's the way of the future (lighter, cheaper, more compact, less complex, and no leaks). It should get better over time, I guess. The method of assistance shouldn't dictate how a rack feels, no?

I would be interested in more feel but don't feel we need more weight to the steering. Particularly in the heavy mode. I also own a 997 and going back and forth between the two, the amount of effort is similar but the Porsche has much more feel. But then again, there isn't a big V8 in the front of the 911 either and the car is a true sports car (vs. sport coupe/sedan for the M3). I don't think the OP is going to get anywhere with this. Even if you could mess with the code to increase the weight/effort of the steering, I doubt many would be interested enough to pay money for it.

Get an under drive pulley-it should stiffen up your steering. This is a fairly common easy and common mod.

Coming from a E46 M3-I actually prefer the steering of the E9X. And for the misinformed folks here-our cars do not have an electric power steering.

FAIL! The new M5 uses hydraulic power steering even though the rest of the new 5 Series lineup uses electric. That too is covered in various magazine articles.

Agreed. The OP is confusing steering effort with feedback and feel.

Tried it. Maybe a bit heavier in effort, but the tactile feedback is not improved.

Is the "sport" power steering setting really that much different that the standard setting? If it is, I wonder if it would be possible to just retrofit that. It seems that would be a more feasible option.

Yes what I meant was weight/heaviness, and not necessarily "feel" in the sense of direct driver feedback feel. Just talking about the heaviness of the wheel which I think would be nice to have a bit heavier
